7.差分端接属性 差分端接属性(DIFF_TERM)用于差分输入I/O,用于打开或关闭芯片内置100Ω差分端接电阻。片上输入端接电阻比芯片外部分立电阻端接更能改善信号完整性,因为片内端接电阻在接收器侧不存在stub(由PCB设计引起,可以通过背部钻孔消除,会带来PCB制造成本增加)。该属性应用于以下I/O标准: LVDS LVDS_25 MINI_

1.打开合成/实施项目,通过选择预期的IO垫并查看其“属性”选项卡,检查是否已应用DIFF_TERM = TRUE。 2.在IO pad上使用get_property tcl命令。 下面的示例显示了检查DIFF_TERM属性的两种方法的屏幕截图。 在这种情况下,属性被应用于并检查DRP时钟。 举报 潘琳 2020-7-24 10:09:23 Siktap 您建议,浏览Vivado ...
diff命令功能。逐行逐行的对文本文件的不同之处进行对比，当我们对比的为目录时，则diff会比较目录中相同文件名的文件。diff预设只会逐行比较文本文件。

工具版本是Vivado2013.4。 我想使用DIFF_TERM。 所以我声明并实例化IBUFDS如下: IBUFDS_DIFF_OUT#(。DIFF_TERM(“TRUE”),. IBUF_LOW_PWR(“FALSE”))data_in(.I(datain_p ),. IB(datain_n ),. O(rx_data_in_p ),. OB (rx_data_in_n [I])); 实施后,我确认了IO报告。 但我找不到DIFF_TER...
该错误提示约束属性中约定了DIFF_TERM_ADV,但是DIFF_HSTL_I_12电平标准不支持。具体的原因笔者不太清楚,但是大概是和电平标准还有BUFG相关。在我的代码中,引入了差分时钟信号clk_p、clk_n,但是需要使用单端信号,因此使用IBUFDS对信号进行了转换。代码如下: IBUF

In UltraScale and UltraScale+ designs generated with Vivado versions up to and including 2016.1, the DIFF_TERM attribute is not reported appropriately, nor is the attribute properly checked to ensure that a valid bank voltage is used when the attribute is defined in the HDL as...
